The Impact

The impact of coal mining in Kuzbass on the ecosystem of the region is studied in the article. Large-scale mining operations have led to land disturbance over large areas. The coal industry development program, which provides for a significant increase in production, will further aggravate the identified problem. There are a lot of reclamation mechanisms, they must be implemented comprehensively, be high-tech. Large-scale disturbance of land resources, and land retirement, its pollution and littering are the most significant problems requiring a primary solution. The mechanism of state and regional legal regulation of disturbed land reclamation is proposed. Improving the quality of reclamation will be facilitated by the development of a strategy for the environmental remediation, which would be included into the Concept for reclamation of disturbed lands.

The mining industry plays a significant role in economic growth and development. Coal is a viable renewable energy source with 185.175 billion deposits in Thar, which has not been deeply explored. Although coal is an energy source and contributes to economic development, it puts pressure on environmental sustainability. The current study investigates Sindh Engro coal mining’s impact on environmental sustainability and human needs and interest. The Folchi and Phillips Environmental Sustainability Mathematics models are employed to measure environmental sustainability. The research findings demonstrated that Sindh Engro coal mining is potentially unsustainable for the environment. The toxic gases (methane, carbon dioxide, sulfur, etc.) are released during operational activities. The four significant environment spheres (atmosphere, hydrosphere, biosphere, and lithosphere) are negatively influenced by Thar coal mining. The second part of the analysis results shows that human needs and interests have a positive and significant relationship except for human health and safety with Sindh Engro coal mining. Environmental pollution can be controlled by utilizing environmentally friendly coal mining operations and technologies. Plantation and ecological normalization can protect the species, flora, and fauna of the Thar Desert. The government of Pakistan and the provincial government of Sind should strictly check the adaptation of environmental standards. Furthermore, the researchers should explore the environmental issues and solutions so that coal mining becomes a cost-efficient and environmental-friendly energy source in Pakistan.

Coal Mining Subsidence

Underground coal mining will inevitably cause land ponding in high groundwater table, which will affect the land sustainable development. However, the traditional reclamation (TR) is poor in land rate. Thus, finding a suitable reclamation approach is crucial to alleviate the conflicts between coal exploitation and land protection. In this paper, taking Guqiao Coal Mine of China was seriously affected by mining-induced ponding as an example. Firstly, dynamic distribution of surface subsidence and land damage from 2007 to 2017 was revealed base on concurrent mining and reclamation (CMR). Second, the land-water layout of five reclamation schemes (no reclamation, TR, CMR I, CMR II and CMR III) were simulated. Then, and the dynamic filling elevation model and filling thickness model were constructed. Finally, the sequence of earthwork allocation was optimized. The results revealed that: 1) reclaimed land area: CMR III > CMR II > CMR I > TR > no reclamation; 2) The digging depth is directly proportional to earthwork volume and land area, and inversely proportional to water area, but with increase of digging depth, the increase in the reclaimed land area relatively slowed down; 3) CMRs had reclaimed 426.31~637.82 ha and 259.62~471.13 ha more than the no reclamation and TR respectively. Compared with the no reclamation and TR, CMRs can increase the proportion of reclaimed land by 33.77~50.52% and 20.57~37.32% respectively. The research results provide a reference to increase the reclamation rate of mining areas in the high phreatic table.

The purpose of the study is to influence land resources during mining operations, and the main stages of land reclamation during mining on the example of the Tyradinsky gold Deposit, the "Zolotaya Tyrada" quarry, located in the Yenisei region of the Krasnoyarsk territory. The main factors of impact on land resources in the process of mining the field are considered; the analysis of measures to reduce the negative impact on land resources in the process of mining the field is carried out. The actual height and area of overburden dump not to exceed project, the reconfiguration of dumps allowed us to reduce the impact of mining on the environment, to avoid placing parts of the dumps in the water protection zone of the river Terada, thus there is no need of land allocation to forests of the first group and reduced the amount of removed topsoil. During the reclamation, potentially fertile soils (loam) taken from the quarry were used. There will be no deterioration in the impact on land resources during the liquidation process, due to the short duration of the work and within the existing land allotment.

Mining Industry is often tagged as a polluting sector since it involves since it involves extensive resource exploitation by unsustainable methods. The techniques involved in mining cause tremendous destruction to the environment and health of people living in nearby areas. There is a growing consensus on sustainable and efficient mineral development which will avoid the clash between economic and environmental interests. Deployment of advanced and sustainable technological solutions in the entire mining process, fixing the gaps in its regulatory mechanisms and learning from the successes of specific domestic and international mining operations are certain solutions that have the capacity this sector more productive. The paper provides insights into the problems of mining sector and possible solutions to overcome these problems. It also provides examples of certain best practices adopted by mining corporations for sustainable coal mining. The paper also explores various methods and technologies which can be adopted by Thermal Power Plants to reduce their emissions and simultaneously conserve environment. An empirical study of Dahanu Thermal Power Station located in state of Maharashtra of India has been undertaken for this purpose to study the modern technologies adopted by them to lower their emission levels.

Coal is one of the most mining commodities to date, especially to supply both national and international energy needs. Coal mining activities that are not well managed will have an impact on the occurrence of environmental damage. This research tried to utilize the multitemporal Landsat data to analyze the land damage caused by coal mining activities. The research took place at several coal mine sites in East Kalimantan Province. The method developed in this research is the method of change detection. The study tried to know the land damage caused by mining activities using NDVI (Normalized Difference Vegetation Index), NDSI (Normalized Difference Soil Index), NDWI (Normalized Difference Water Index) and GEMI (Global Environment Monitoring Index) parameter based change detection method. The results showed that coal mine area along with the damage that occurred in it can be detected from multitemporal Landsat data using NDSI value-based change detection method. The area damage due to coal mining activities  can be classified into high, moderate, and low classes based on the mean and standard deviation of NDSI changes (ΔNDSI). The results of this study are expected to be used to support government efforts and mining managers in post-mining land reclamation activities.

In the paper the influence of surface mining on the environment is presented. The sizes of mining areas and depression funnels has been shown. Also are presented the amount of cover materials and the quantity of water pumped out from the mines in five regions of brown coal mining in Poland.Various conceptions of land reclamation are discussed, from the method of pioneer vegetation in the years of 1950 - 1970, trough selective excavation of the humus soil in the years 1970 - 1980, to conception of the direct introduction of the final type of vegetation.In the lost part of the paper three models of agricultural land remediation are discussed, as well as the yields of the cultivated plants on recultivated former mining areas.
